Abstract: An example system for building a modular wall structure includes at least one wall unit and at least one pillar. Each wall unit has top and bottom surfaces, opposed first and second side surfaces, first and second ends, and a projection disposed on each end extending outwardly from the first and second side surfaces. Each pillar has a top and bottom surface configured to be vertically stackable, and at least one vertical groove comprising, in section, a wall unit accepting opening open to an outer vertical surface of the pillar and continuous with a wider projection accepting opening disposed inwardly of the wall unit accepting opening When the projection is inserted into the vertical groove, the projection can rotate within the projection accepting opening.

Abstract: Detailed herein is a technology which, among other things, provides for forward chaining in a ruleset. In one approach to this technology, a first rule is examined, to identifying a data object associated with it. A second rule is identified, also associated with the data object. The relationship between the two rules is determined, where execution of the second rule will modify the data object, which, in turn, will alter the outcome of the first rule.

Abstract: Described herein is technology for, among other things, enabling use of custom expressions in a rules engine. The rules engine may be used in conjunction with a workflow. The technology involves providing a custom expression with access to validation context and execution context of the workflow. The custom expression can then participate in rules engine validation and execution. Furthermore, the technology allows for variables of the custom expression to be analyzed so that the rules engine can discover the variable dependencies of the custom expression and any side effects that drive forward chaining.

Abstract: Various technologies for integrating workflow services are described. In accordance with one described embodiment, an integrated workflow services system includes a host process, such as a Windows® application program. The host process hosts a workflow foundation runtime engine for executing workflows and a workflow foundation library. A workflow executable by the workflow foundation runtime engine may include an activity (e.g., a policy activity) that defines a ruleset that includes a number of rules (e.g., business rules). At least one rule of the ruleset is defined directly against the workflow. Furthermore, the activity has access to a rules engine capable of evaluating rules in the ruleset.

Abstract: A high pressure electrical cable packoff and method of making. An integral packoff and seal includes a resin block bound to the insulation of an electrical cable where the metal exterior and jacket have been removed. A resilient sealing ring is molded around and encloses the block and the section of cable where the metal exterior and jacket have been removed. The integral packoff may be used in a wellhead in an oil well for restraining movement of the cable and for forming a high pressure seal.
